Title: Semiconductor integrated circuit device
Inventor: KAWACHI TOSHIHIKO
IPC: H01L21/302
Filed: 1990-11-27
Abstract: PURPOSE:To obtain a passivation film whose film thickness is uniform and to enhance reliability by a method wherein the title device contains the following: a sidewall insulating film which is formed so as to bury the difference in level on the surface; and the passivation film which is grown on the whole surface of a substrate including a metal interconnection for external extraction use and the insulating film. CONSTITUTION:Sidewalls 7 for a passivation film are formed in advance on side-face parts of a metal interconnection 8 for external extraction use; the passivation film 9 is formed on them. That is to say, the passivation film 9 is formed as a two-layer smooth structure. Consequently, when a passivation film 9 is applied onto it again, it is grown to a uniform thickness in which the difference in a film thickness is hardly caused because no abnormal growth operation is performed. Consequently, it is possible to obtain the passivation film 9 in which there exists no danger that a contamination creeps. Thereby, it is possible to solve a danger that reliability is lowered due to the abnormal growth of the passivation film.

Title: Solenoid valve
Inventor: HIRAISHI KAZUO
IPC: F16K31/42
Filed: 1992-12-08
Abstract: PURPOSE:To provide a solenoid valve having the capability of maintaining sufficient operation stroke, and operating on micro current. CONSTITUTION:A plunger laid within the vertical aperture of an electromagnetic coil 11 in such a way as free to advance and retreat is made of a main plunger 25 and a sub-plunger 26 for adsorbing the main plunger 25 in an excited condition. Also, the ascending motion of the sub-plunger 26 is interlocked with the substantial rise of a diaphragm 45 via a sub-plunger operation lever 32. Consequently, the supply of micro current to the coil 11 is required to raise the plunger only by a micro distance for normal operation, thereby saving power consumption. Also, the plunger can be made to substantially ascend using the substantial rise of the diaphragm 45 and, therefore, the stroke of the main plunger 25 can be further enlarged, thereby enabling a large flowrate to be maintained with a solenoid valve B.

Title: Semiconductor light-emitting element and manufacture thereof
Inventor: NOGUCHI HIROYASU
IPC: H01L29/06
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To inhibit a build-up of the center of a non-radiative recombination due to point defects by inhibiting the movement of the point defects and to prolong the life of a semiconductor light-emitting element. SOLUTION: A plurality of lattice mismatching layers 13 having a grating constant smaller than that of an active layer 6 are inserted in the active layer 6. The rate of a lattice mismatching of each lattice mismatching layer 13 to that of the active layer 6 is within 10% and the thickness of each lattice mismatching layer 13 is the thickness or shallower of 10 atomic layers. The thickness of the layer 6 held between the layers 13 and the thickness of the layer 6 held between the layer 13 and a first guide layer or the thickness of the layer 6 held between the layer 13 and a second guide layer are respectively the thickness or shallower of 10 atomic layers. As the side of the interior of the layer 6 having the large grating constant is stable in an energy manner to hole type point defects 14, it can be inhibited that the point defects 14 exceed the layers 13 to move. As each film thickness of the layer 6 is thin, the movement of the point defects 14 in the thin films of the layer 6 can be also inhibited.

Title: Treatment of mixed compound rubber strip
Inventor: KURITANI HIDEO
IPC: B26D7/32
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To enhance slitting workability and to reduce the irregularity of divided sheet width by kneading mixed compd. rubber to form the same into a strip and performing slitting fitted with a plurality or more of dividing perforations immediately after a sheet roll to hold the width of the whole. SOLUTION: Mixed compd. rubber is kneaded within a Banbury mixer to be passed through the nip between two sheet rolls to form a strip and slitting fitted with two or more perforations is applied to the strip on the conveyor before a dusting tank without dividing the strip into two. In this stage, since sheet width is large and the left and right parts of the strip are connected because only perforations are applied, the meandering of the sheet is reduced and, since the center is positioned almost at the center and sheet rubber is divided in a heated state, slitting workabllity is also enhanced. Further, perfect bisecting slitting is not performed and the total sheet width is partially connected because of perforation applying processing and stability is well and there is no collapse in handling and transport.

Title: Float-up melting device for continuous casting
Inventor: KAINUMA KENGO
IPC: B22D11/124
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high pure cast billet without mixing foreign matter by plugging a flow-out hole with a base material having the same material as melting material, cooling the discharged molten metal with non-contacting state and descending the cast billet at a fixed speed. SOLUTION: The molten metal 1 in a crucible 7 is discharged from the flow-out hole 7a by controlling the electric currents of an upper induction coil 8a and a lower induction coil 8b and descended downward at the fixed speed together with the base material 6 with pinch rolls 4 and cooled and solidified by gas-injecting from a gas injection type cooler 10 on the way, and cast to a cast billet 5. The base material 6 has the same material as the molten metal 1 and uses at the initial stage of the casting. Then, since the molten metal 1 discharged from the flow-out hole 7a generates electromagnetic resiliency to eddy current flowed in the inner peripheral side of the flow-out hole 7a, the contracting force is received during passing through there.  Further, since the molten metal can directly and continuously be cast from the crucible and is not brought into contact with a mold and the cooler, the wearing caused by casting is not developed, and the maintenance can be facilitated.
